im a total newbie to this and i got this error below while publishing my app. any tips on how to fix ? i think most of the lines will get solved by creating a venv which i didnt create earlier... but the keyerror is what im concerned about.

KeyError: "[('Close', 'BTC-USD')] not in index"

Traceback:

KeyError is a Python error that happens when you try to access a dictionary field with a key that doesn't exist.

You said your issue was when publishing, but it looks like it wouldn't run locally either. Based on your error message, it looks like keep in df[keep] doesn't exist.

Edit: and just to comment on what you said about using venv, this is actually all one traceback for the single KeyError you got. It doesn't seem to have something to do with the environment, unless the server is interpreting a Pandas data frame as a dictionary, or something like that.

Let me know what you find out and I'll try to help.
